Deduce the molecular masses of those compounds:Atomic masses – H(l),

1.	Deduce the molecular masses of those compounds:Atomic masses – H(l), 0(16), N(14), C(12), K(39), S(32) Ca(40), Na(23), Cl(35.5), Mg(24), Al(27)Molecular formula – MgCl2
Answer» Molecular mass of MgCl₂ (M) = (Atomic mass of Mg) x 1 + (Atomic mass of Cl) x 2 = (24 x 1) + (35.5 x 2) = 24 + 71 = 95 ∴ Molecular mass of MgCl₂ (M) = 95 MgCl molecular mass of MgCl = Atomic Mass of Mg + Atomic Mass of Cl =24+35.5 =59.5

Answer»

Molecular mass of MgCl₂ (M)

= (Atomic mass of Mg) x 1 + (Atomic mass of Cl) x 2

= (24 x 1) + (35.5 x 2)

= 24 + 71

= 95

∴ Molecular mass of MgCl₂ (M) = 95

MgCl

molecular mass of MgCl = Atomic Mass of Mg + Atomic Mass of Cl

=24+35.5

=59.5
